Any penetration in a metal roof offers the potential for leaks if it is not flashed properly, and a chimney is no different.
Today on The Metal Roofing Channel, Matt Lane from Metal Construction Solutions and Installations shows how to flash a chimney on a standing seam metal roof using a pre-manufactured curb. The curb is made of welded aluminum and gives superior lifetime protection, and is installed onto the chimney by way of a reglet flashing.
